Since ancient times, East Asia and Central Eurasia have been connected to the world. Nationalist histories, however, have focused on the internal ‘unity’ of each of the nation-states of East Asia — China, Korea, Japan, and Vietnam — while Central Eurasia has been fragmented into ‘Inner Asia’ (Mongolia, Tibet, Xinjiang, and Manchuria) and ‘Central Asia’ (former soviet Central Asia). These arbitrary divisions ignore similarities and interactions within Asia, and they no longer fit the post-1989 world. Globalization and nationalism have now developed together. Nevertheless, East Asia and Central Eurasia have a much longer history of cultural and economic interaction than of nationalist isolation. This article suggests way to study the global connections of East Asia and Central Eurasia. It considers state contacts, stat formation and expansion, and great divergences between nations.
